Reverb (short for reverberation) is the acoustic environment that surrounds a sound. Natural reverb exists everywhere. Whether the space being described is a bathroom or a gymnasium, the essential characteristics remain the same. Reverb is composed of a series of tightly-spaced echoes. The number of echoes and the way that they decay play a major role in shaping the sound that you hear. Many other factors influence the sound of a reverberant space.
Vascular calcification (VC) is a predictor of cardiovascular morbidity and mortality. Hemodialysis (HD) patients suffer from severe vascular calcifications. Matrix Gla protein (MGP) is a central calcification inhibitor of the arterial wall and its activity depends on vitamin K-dependent Î³-glutamate carboxylation. Noncarboxylated MGP, formed as a result of vitamin K deficiency, is associated with cardiovascular disease.
The human leukocyte antigen system or complex is a gene complex encoding the major histocompatibility complex proteins in humans. These cell-surface proteins are responsible for the regulation of the immune system in humans. The HLA gene complex resides on a 3 Mbp stretch within chromosome 6p21. HLA genes are highly polymorphic, which means that they have many different alleles, allowing them to fine-tune the adaptive immune system. The proteins encoded by certain genes are also known as antigen
